SQL選擇的ID，是不是在另一個表，除非該寄存器具有一定的列數據

Question

我有以下SQL：

SELECT id FROM order o 
INNER JOIN order_payment p ON p.parent_id=o.entity_id 
WHERE o.state='new' 
AND o.created_at BETWEEN '2013-05-14' 
AND '2013-10-11 00:19:09' 
AND p.method IN ('paymethod_a', 'paymethod_b', 'paymethod_c') 
--AND o.id NOT IN (SELECT id FROM order o 
--INNER JOIN payment_method pm ON pm.order_id=o.id 
--WHERE o.created_at BETWEEN '2013-05-14' AND '2013-10-11 00:19:09')** 

在註釋部分，我不想得到任何標識的哪在表payment_method.order_id（外鍵）上也匹配。 但是現在，系統更新改變了一些事情：現在我想在註釋區域獲得相同的結果，PLUS：如果payment_method寄存器有'status = 0'列，我也必須得到該id，如果命令.id在payment_method.order_id（外鍵）上。

我吮吸SQL，任何人都可以幫助我嗎？ 謝謝！

Answer 1

通常情況下，NOT IN（子查詢的查詢）上表現不佳。相反，做一個LEFT-JOIN會更好，如果另一個表是NULL（表示不存在），則接受該記錄。如果您想包含其他特殊情況，這也有助於您的狀況。例如：

SELECT 
     o.id 
    FROM 
     order o 
     JOIN order_payment op 
      ON o.entity_id = op.parent_id 
      AND op.method in ('paymethod_a', 'paymethod_b', 'paymethod_c') 
     LEFT JOIN payment_method pm 
      on o.id = pm.order_id 
    where 
      o.state='new' 
     AND o.created_at BETWEEN '2013-05-14' AND '2013-10-11 00:19:09' 
     AND (pm.order_id IS NULL 
      OR pm.status = 0) 

Answer 2

考慮到要參加3個不同的表審議幷包括與狀態0

SELECT id FROM order o 
INNER JOIN order_payment p ON p.parent_id=o.entity_id 
INNER JOIN payment_method t3 ON t3.order_ID = o.orderID 
WHERE o.state='new' 
AND o.created_at BETWEEN '2013-05-14' 
AND '2013-10-11 00:19:09' 
--query modified,if there are only one parameters,Function 'IN' is not supported 
AND p.method = 'payment_method' 

--you never exclude status = 0 in payment_method table, so nothing is needed to do at all
